LEWIS T. DEUBLER, OF SCRANTON, PEINSYLVANA CANOPY FASTENER Application filed April 9, 1932. Serial No. 604,309.

This invention relates to lighting fixtures and more particularly to an improved canopy supporting means which can be readily mounted on an outlet box engaged with a ceiling or other wall construction.

Another object of this invention is to provide a fixture of this kind which is so constructed that it `can be attached or removed from the outlet box without the use of any i6 screws or bolts, thereby eliminating the possibility of the fixture becoming loosened due to vibration or the like.

The above and various other objects and advantages of this invention will in part be 1. described in and in part be understood from the following detailed description of the present preferred embodiment, the same being illustrated in the accompanying drawing, wherein f, Figure 1 is a fragmentary detail perspeo tive View of a device constructed according to the preferred embodiment of this invention.

Figure 2 is a fragmentary sectional View .,5 showing the detachable securing means for attaching the fixture to the outlet box.

Figure 3 is a detail side elevation of another form of attaching bar which is connected to an outlet box. .0 Figure 4 is a fragmentary sectional view partly in detail showing a modified form of securing the locking members on the casing of the fixture.

Referring to the drawing wherein like nu-V merals of reference designate corresponding parts throughout the several views, the numeral 10 designates a lighting fixture or canopy which is provided with a substantially cylindrical base 11 which is adapted to engage the outer surface of a ceiling or wall.

An attaching bar, generally designated as 12, which is provided with a. fiat top portieri 13 and downturned end portions 14, is adapted to be attached to the outlet box, the bar 13 having elongated slots 15 therethrough for receiving the conventional securing bolts whereby the bar 13 may be secured to the outer surface of the outlet box. 14n opening 16 is provided at substantially the center of the bar 13 for attaching the bar to the central stud conventionally provided in outlet boxes.

1n order to removably attach the canopy 10 to the bar 12, l have provided a. pair of arcuate and resilient securing members which are generally designated as 17, and which has one end -19 riveted or secured, as at 18, to the inner surface of the flange 11. The central portion of the securing member 17 is offset, as at 20, andthis oflsetportion is adapted to engage the depending lug 14 of the bar or bridging member 12. The terminal end 21 of the securing member 17 is outwardly offset and inturned, as at 21, so as to provide a means for facilitating the positioning of the securing member 17 on the depending lug 14.

rlhe lug 14 is provided with an inwardly extending lug 22 which is vstruck from the body of the lug 14, and this lug 22 is preferably disposed in parallel relation to the P bridging member 13. The securing member 17 is adapted to engage between the lug 22 and the horizontal bar 13 so as to prevent vertical movement of the canopy 11 relative to the bridging member 12.

As shown in Figure 4, the securing member 17 provided with a reverted end portion 23 which ext-ends through an opening 24 provided in the baseriiange 11, and this reverted portion 23 is crimped or otherwise tightly pressed against the flange 11 so as to securely hold the resilient member 17 in adjusted position.

1n Figure 3, there is shown a modified form of bridging member 12 wherein the opposite end portions of the horizontal bar 13 are bent downwardly at a right angle, as at 25, so as to offset the lugs 14 downwardly from the horizontal bar 13. These lugs 14 are provided with inwardly extending lugs 22 between which and the horizontal extensions 26, the resilient securing members 17 are adapted to be positioned for removably mounting the canopy on the bridging member 12. y

1n the use of this device, the attaching bar or bridging member 12 may be first attached to the outlet box by `passing screws or the like through the slots 15. When the bridge or attaching bar 12 is firmly attached to the outlet box, the canopy may be disposed with the base about the lugs 14 and the base then given a partial rotary movement so as to permit the securing members 17 to be disposed between t-he inwardly extending lugs 22 and 5 the horizontal bar 13.

It will, therefore, be seen that the canopy l0 can be readily mounted on or detached from an outlet box without the use of tools and that the canopy 10 will be securely maintained in adjusted position relative to the outlet box.

It is, of course, understood that various changes and modifications may be made in the details of construction and design of the above specifically described embodiment of this invention without departing from the spirit thereof, such changes and modifications being restricted only by the scope of the following claims.

lVhat is claimed is l. In combination, a canopy including a substantially cylindrical base, a flat bar disposed diametrically of the base and having openings therethrough to receive securing bolts to secure the bar to an outlet box, a flange carried by each end of the bar and adapted to engage the inner surface of the base, a second flange carried by the first flange and 3U disposed in parallel relation to the bar, and

a pair of yieldable members mounted on the base and engaging between said second fla-nge and the bar to releasably lock the canopy on the bar. 1;.3 2. In combination, a canopy including a substantially cylindrical base, a flat bar adapted to be secured to an outlet box, downturned flanges carried by the bar and adapted to engage the inner surface of the base, a yieldable locking member carried by the base, means for securing one end of the member to the base whereby to permit movement of the other end relative to the base, and an inwardly extending member carried by each #l5 flange downwardly spaced from the bar, said latter member coacting` with the locking member to releasably lock the base on the bar. 3. In combination, a canopy including a base of substantially cylindrical construction, 5U a member having slots therethrough to permit attachment thereof on an outlet box, flanges carried by the member and engaging the inner surface of the base, an inwardly extending lug carried by each flange, a yield- 55 able member, means for securing one end of the yieldable member to the base whereby to permit movement of the other end, and an outwardly extending locking member carried by the yieldable member and adapted to releasably engage on one side of a flange.

In testimony whereof I hereunto aflix my signature.

LEWIS T. DEUBLER.
